Hi Werner,

Thanks for your reply.

Interestingly the Bootloader wiki page uses write.e for all of the examples 
except the one for reflashing the bootloader 
(http://wiki.openmoko.org/wiki/Bootloader#Writing_new_bootloader_to_NAND).

Unfortunately the USB console seems to no longer be operational. I 
have /dev/ttyACM0 when the device is plugged in at the menu, but connecting 
to it and pressing enter in the terminal does not give any response. I don't 
have a debug board so I can't try serial. As I mentioned previously the menu 
does not have the console options since I reflashed.

I could use dfu-util to flash a new copy of the bootloader, but of course 
u-boot is in "u-boot Runtime Mode" and therefore only lists one target for 
downloading - does that matter?

Cheers,
Paul
